/* ============================================================================
   AGLE — stage stylesheet

   The scroll runtime (source/app.js) writes a small set of custom properties
   onto <main class="story-page">:

     --fw --fh --fr      vessel width / height / corner radius, in px units
     --fit               uniform scale that keeps the vessel inside the stage
     --morph             0 at rest, 1 at the peak of a shape change
     --sheen --turn      specular sweep position, 3D turn direction
     --in-<panel>        how present each panel's content is (0..1)
     --fill-<panel>      how far through its dwell that scene has scrolled
     --sg --sga          extracted signals: emit / absorb
     --sc --scp --scr    source systems: emerge / prove / retract
     --sealed --verdict --meter --intro --atmosphere --progress

   Everything else — per-row unfolds, orbit trajectories, staggers — is derived
   from those with clamp() math, so a frame costs ~25 property writes and no
   React work.
